6 FAQs about [Where are the welding points of photovoltaic panels ]

How to string Weld a solar panel?

4.3.1 String Welding Procedures during Solar Panel Production Follow these procedures when string welding a solar panel: Check for the defects on the cell. These include improper angle, lack of edge, and the poor state of the welding belt. Put the solar panel cell into the material box and start to circulate.

Why do solar panels need welding?

Welding is used to mass-produce solar panels as it will easily join the aluminum, copper, glass, and other materials used in solar panels. High-energy density welding is preferred as it can focus energy into extremely small-sized and sensitive areas. 3. Assembling

How welding strip affect the power of photovoltaic module?

The quality of welding strip will directly affect the current collection efficiency of photovoltaic module, so it has a great impact on the power of photovoltaic module. The so-called photovoltaic welding strip is to coat binary or ternary low-melting alloy on the surface of copper strip with given specification.

How to reduce the shading area of a photovoltaic welding strip?

The shading area of the photovoltaic welding strip is reduced by reducing the width of the main grid line and the PV welding strip, and the total amount of light received by the solar cell is increased. However, the contact resistance of the whole PV assembly is too large, which increases the electrical loss of the photovoltaic module.

What are the physical properties of solar cell welding materials?

The thickness of silicon wafer is 160 μm, the thickness of PV copper strip is 0.1 mm, the thickness of Sn alloy coating is 15 μm and 25 μm respectively. The physical properties of materials used in solar cell welding are shown in Table 6.

Can solar cells be used in photovoltaic modules?

Connection of Cells in Photovoltaic Modules. As shown in Fig. 5, the solar cells in the modules with different surface structures of welding strips have no cracks, and there is no open welding, false welding and desoldering, which indicates that it can be used for the subsequent research.
